L. KOOPERSTEIN LIQUID SOAP DISPENSING DEVICE Filed Feb. 8, 1929 ATTORNEY Patented Nov. 12, V1929 UNITED STAI LOUIS KOOPERSTEIN,VK or ASTORIA, 'NEW YORKQASSIGNOR Tol wnSTVnISINrnoTINa COMPANY, or LONG ISLAND CITY, NEW YORK, A CORPORATION orfNnw Yoan v Application filed February 8, 1929. Serial No. 338,481. i

The Object of the present invention is to vprovide a dispensing apparatus ior liquid soap of a type comprising a plunger-operated discharge device which receives the liquid soap from a bowl mounted thereon, the soap tlowing into the operating device by gravity.

The specific object of Vthe invention is to employ a glass bowl for the liquid soap in conjunction with means for securing the bowl to the discharge deviceV in such a manner that replacement of the bowl may be readily effected and a new bowl may be applied merely by fitting the bowl into position and turning a Screw which may be reached by a screw driver through the Open top of the bowl. 'Ihe arrangement enables a very shallow seat for the bowl on the plunger operated discharge device, and the elimination of screw threads on the bowl at the base' thereof.

The invention will be described with reference to the accompanying drawing in which Fig. 1 is a side elevation oan embodiment of the invention, the bowl and its retaining devices beingshown in vertical sections g Y Fig. 2 is a fragmentary elevation of the lowlpr portion of the `bowl and its retaining dis v Y Fig. 3 is a fragmentary view of the plunger discharge device and its Seat for the bowl,l

In the drawings 1 indicates the plunger operated discharge device. Vhorizontal member having a flanged eXten-V It consists of a sionv 1 by means of which the device maybe secured to a support by the screws 2. 'Ihe de* vice is formed with an internal bore 3 for containing the valve mechanism, said mechanism forming no part of the present invention and not being shown. The mechanism is actuated by a plunger l and the soap is discharged through a nozzle 5. v

vThe top of member 1 is formed with an Vannular seat 6 having the upwardly' projecting flange 7. v'Ihe seat 6 is-ormed with passageways 8 permittingthe soap to flow down into bore 3. The seat is also formed later to' be explained.

The bowl is shown at 10. It consists of a glass body having an annular anged and threaded upper neck 11, adapted to receive a closure cap12. Intermediate the cap and top edge of the bowl may be placed a washer 13.

At its base the bowl is formed with an annular shallow depending neck 12X at the top of which is a horizontal annular shoulder 14.

Cemented upon neck 12? of the bowl is a` retaining cup 15, preferably of kmetal, the upper wall of which engages annular shoulder 14C. Retaining ycup 15 is formed with openings 14X adapted to lie in register with openings 8. Y

In order to insure that the bow will be accurately placed in position so that the openings 14X will lie in register with opening 8, f,

located' threaded aperture to receiveA -with a threaded aperture 9 for the purposes the cup and thence into threaded aperture 9 Y of the annular seat. a stop nut 18x so that when the screw is ro- On screw 18 is threaded v tated to withdraw its threaded'end from anl nular seat 6, the screw will be retained in position on the retaining cup 15.

Retaining cup 15 l nished to insure smooth contact with Vthe walls of annular seat 6.

Having described ymy Vinvention what I claim and desire to secureby Letters Patent is as follows valve casing formed withan annular flanged seat provided with soap apertures and with a y threaded aperture, in combination with a may be made of metall 1. In liquid soap dispensing apparatus a y bowl having an upper neck opening adapted Y Y to be closed by a filler cap and a lower relacementedupon the last named neck and havtively shallow neck, an annular retaining cup ou ing a soap aperture adapted to lie in register Y with the aperture of said seat and provided Vwith a screw aperture, and a holding screw e for securing the retaining cup to said seat,

the screw being in vertical alignment with the filler neckl opening. Y p

2. A device constructed in accordance with claim l in which the retaining cup and seat are provided with inter-engaging lug and socketdevces adapted t0 Inaintainthe soap apertures in register;v` f

yIn testimony whereof, I have signed my name to this specification.
